Why no RUNNING interface on Solaris ?

[Database Administrator]

Hello,
Apologize for topic, but I have very strange situation with Netra
Solaris 5.9 and its network interfaces.
I use four ports build card (bge0-3) and want to configure just two
bge0 and bge1.
When I reboot the server I see that port on my switch is live till I
see Openwindow prompt to login.
After login and isse a command ifconfig -a I see three entries:
lo0: flags=1000849 mtu 8232 index
1
inet 127.0.0.1 netmask ff000000
bge0: flags=1000843 mtu 1500 index 2
inet 3.111.0.9 netmask fffffc00 broadcast 3.111.0.255
ether 0:14:4f:b8:b9:40
bge1: flags=1000843 mtu 1500 index 3
inet 3.222.0.8 netmask fffffc00 broadcast 3.222.0.255
ether 0:14:4f:b7:f9:60
As you can see no RUNNING flag.
I did:
ifconfig bge0 down
ifconfig bge1 down
ifconfig bge0 unplumb
ifconfig bge1 unplumb
ifconfig bge0 plumb
ifconfig bge0 3.111.0.9 netmask 255.255.252.0
ifconfig bge1 3.222.0.8 netmask 255.255.252.0
Then ifconfig -a returns:
lo0: flags=1000849 mtu 8232 index
1
inet 127.0.0.1 netmask ff000000
bge0: flags=1000843 mtu 1500 index 2
inet 3.111.0.9 netmask fffffc00 broadcast 3.111.0.255
ether 0:14:4f:b8:b9:40
bge1: flags=1000843 mtu 1500 index 3
inet 3.222.0.8 netmask fffffc00 broadcast 3.222.0.255
ether 0:14:4f:b7:f9:60
But after I up interfaces
ifconfig bge0 up
ifconfig bge1 up
RUNNING disappears from ifconfig state and ifconfig returns:
lo0: flags=1000849 mtu 8232 index
1
inet 127.0.0.1 netmask ff000000
bge0: flags=1000843 mtu 1500 index 2
inet 3.111.0.9 netmask fffffc00 broadcast 3.111.0.255
ether 0:14:4f:b8:b9:40
bge1: flags=1000843 mtu 1500 index 3
inet 3.222.0.8 netmask fffffc00 broadcast 3.222.0.255
ether 0:14:4f:b7:f9:60


I read thread: http://tiny.pl/ss2f but my server is connected (only
bge1 now) to the network.

Thank you ,
